     [摘要]目的:评估即刻种植的近期临床效果及软组织的美学形态。方法:30例患者共35个牙位拔出患牙,同期植入种植体35枚,种植手术过程中测量并记录牙龈附着高度及骨水平高度,种植3~6个月后进行二期手术测量上述指标,同时拍摄根尖片,计算牙槽骨吸收高度,按常规取模、戴牙,对比牙龈附着手术前后美学效果及患者满意程度。结果:所有种植体二期均形成良好骨结合。种植后9个月牙槽骨唇颊侧骨板近、远中吸收量分别为1.2mm和1.0mm。种植修复后3个月牙龈乳头近、远中牙龈附着退缩量分别为0.45mm和0.43mm,患者满意度达97%,临床效果良好。结论:即刻种植临床效果与常规种植无明显差异,软组织美学更佳,可以进行推广和应用,远期效果仍有待观察。

    Abstract:Objective To evaluate the clinical and aesthetic results of immediate implants within 3~6 months after restoration. Methods 30 cases were performed an operation of immediate implant for 35 dental implants as soon as the teeth roots were extracted, surveyed and recorded the bone level and the gingival attachment level during the operations.All cases were performed a delayed restorations in 3~6 months and observed the above indexes at least 3 months,Then evaluated the clinical results and patients' satisfaction. Results All the implants were well osseointegrated when at the second stage operation,Radiographic examination yielded 1.20 mmmedial and 1.0mm distal bone level loss respectively while the medial and distal papilla shrinkage were 0.45 and 0.43 respectively.Patient's aesthetic satisfaction was up to 96.6%. Conclusion The immediate implantation which has no difference between the delayed implantation in 3~6 months after the restoration and also has a better aesthetical result which can be considered to be a valuable treatment option.

    种植义齿日渐成为一种常规的牙列缺损和牙列缺失的修复方法, 我们十年以上的临床研究显示,其成功率大于90%。传统种植学理论要求:拔除患牙3个月以后方可进行种植体植入术,种植术3~6月后才能进行二期治疗及牙冠修复。因治疗周期过长,造成部分患者难以接受种植义齿的治疗方案,特别是前牙美学区牙齿缺失者,因长时间影响生活、工作和社交,往往造成困惑。即刻种植技术的出现,解决了种植修复时间过长这一大缺点,同时最大程度保存了牙槽骨的高度、宽度和丰满度,能够实现良好的软硬组织美学效果。本研究对此技术的应用进行了探讨。

    1材料和方法

    1.1材料和仪器:①种植系统及种植机:3I、BEGO、OSSTEM,Kavo种植机;②器械:种植常规手术器械、牙周膜分离器、微创拔牙器械、骨凿、骨扩张器、牙周探针、常规口腔检查器械、游标卡尺,碳纤维刮治器;③生物材料:Bio-gide胶原膜、Bio-oss人工骨粉 (欧斯海斯)。

    1.2纳入标准:2009年9月~2010年12月,西安交大口腔医院种植中心30例患者,35颗患牙行即刻种植,后期完成冠修复者。3个月后最终对软硬组织的变化情况进行评估。适应证:①伴有少量骨缺损的外伤患牙;②根折后残根无法继续治疗,需拔除者;③广泛龋坏 ......
